Polytechnic

You should pursue polytech in architecture. Instead of this, it is better to go for polytechnic in civil.

I think a place doesn't matter for education.
The things that matter are all about colleges like its facilities, faculty, placement and other such factors.

Hello Sandy,
Definitely she can pursue her Bachelors from India. For that she has to apply to the universities and then apply for study permit in India. Once the study permit is issued, she will be eligible to study here. And one more thing, fees will be pretty high for international students.
All the best.

It has a good value and you can get entry level jobs through it. You may either opt for B.Tech through lateral entry or continue working and opt for engineering through distance education.

Yes, but you have to crack JEE advance exam.
